Ceiling cooling or heating apparatus
a cooling or heating device and ceiling technology, applied in lighting and heating devices, heating types, mechanical machines/dredgers, etc., can solve the problems of significant influence of loss of contact the loss of contact significantly affecting the heat exchange between the ceiling tiles and the straight tubes, and the strain placed on the straight tubing as well as the glue, or clips, etc., to achieve the effect of minimizing any stress or strain

Benefits of technology
It is another object of the invention to provide heating or cooling apparatus for a suspended ceiling that maintains contact with the suspended ceiling in a manner that minimizes any stress or strain on the cooling or heating apparatus if glued or bonded to the ceiling.
The above and other objects are achieved by providing a suspended ceiling with one or more ceiling tiles that are heated or cooled by a heat exchange fluid circulating through spiral shaped coils. The ceiling files are preferably thin pieces of perforated sheet metal fabricated from galvanized steel. The perforated sheet metal may be lined with an acoustical backing. Each spiral shaped coil is preferably flattened so as to provide a flat contact surface with the ceiling tile The spiral shape allows the coil to maintain substantial contact with the ceiling tile when the ceiling tile flexes, bends or sags due to any flexing, bending or sagging of the suspended ceiling.
Problems solved by technology
This causes the ceiling tiles to lose contact with the straight tubes.
This loss of contact significantly impacts the heat exchange between the tiles and the tubes.
This has resulted in considerable strain being placed on the straight tubing as well as the glue, or clips holding the tubing to the tiles when the ceiling sags due to the weight being carried by the suspended ceiling.

Embodiment Construction
Referring to FIG. 1, a room 10 is seen to include a suspended ceiling comprising a number of ceiling tiles, such as 12, each individually mounted within a ceiling support structure 14. Each ceiling tile 12 is preferably made of galvanized steel sheet metal that is five to eight tenths of a millimeter thick. The sheet metal is preferably perforated with holes having a diameter in the range of one-half to three millimeters. The resulting holes preferably constitute between ten and thirty percent of the total exposed surface of the tile 12.
Referring to FIG. 2, the top side of the ceiling tile 12 is illustrated relative to a coil 16 that is to be positioned on the top surface of the ceiling tile 12. The top side of the ceiling tile 12 is seen to include a thin acoustical lining 18 glued to the perforated galvanized steel sheet 20 having the one-half to three millimeter diameter holes 22. The acoustical lining is preferably two tenths of a millimeter thick and consists of a cellulose gla...

Ceiling apparatus for heating or cooling a space includes one or more spiral shaped coils mounted to individual thermally conductive ceiling tiles suspended above the space to be heated or cooled. The spiral shaped coils are interconnected by flexible hose connections so as to define one or more paths of a heat exchange fluid flowing through the coils so as to provide or remove heat from the ceiling tiles.
Description
This invention relates to cooling or heating apparats to be used with suspended ceiling configurations in a home, office or other commercial or industrial buildings.It has heretofore been known to mount relatively thin metal tiles in a suspended ceiling configuration of a room or space and to provide apparatus for cooling or heating such mounted tiles. The heating or cooling apparatus typically comprises straight tubes which run back and forth over the top surfaces of the tiles. The tubes usually contain flowing water having a regulated temperature sufficient to provide heat to or remove heat from the tiles so as to thereby maintain the tiles at a temperature sufficient to radiantly heat or cool the room.It has been found that the thin tiles in such a suspended ceiling configuration do not necessarily remain flat. In particular, the tiles will tend to follow the curvature of the suspended ceiling as it flexes, bends or sags due to the weight of the tubes and other loads being carrie...
